Is it possible to use Yahoo mail using IMAP on emClient. I tried configuring the settings, the mail works fine, but when I enable Calendar Sync, it throws “Server unauthorized” error. I understand that this may be due to avast scanning SSL connections. Is there a fix to this, other than disabling avast scanning SSL?
Hello,
Unfortunately we do not know about any other solution that disabling SSL scanning at this moment 
with regards
Jan
